Examine the following multiplication:
159
x48
7632

In this multiplication, each of the nine digits was used only once. Can you find another similar multiplication, where each digit is used once?

There are plenty more.

Here are all of them ( I hope):

138 * 42 = 5796
157 * 28 = 4396
159 * 48 = 7632
186 * 39 = 7254
198 * 27 = 5346
297 * 18 = 5346
483 * 12 = 5796
1738 * 4 = 6952
1963 * 4 = 7852

Ya, I must be autistic or something because I can't leave these things alone.
